Can't build bug------> Really quick fix and important (For Admins)

The server is Facepunch London 1 …Basically every time you try place a fire or try to build, it shows and error …Please restart the server!!!

Its reached the entity limit. A restart might knock a few unstable buildings down and fix it for a few minutes. The server needs a wipe. Problem is, monthly wipe is due Thursday so a wipe now will kill the server for a week.
